Tan 2 (t) 1 = sec 2 (t) 1 cot 2 (t) = csc 2 (t) Advertisement Note that the three identities above all involve squaring and the number 1 You can see the PythagoreanThereom relationship clearly if you consider the unit circle, where the angle is t, the "opposite" side is sin(t) = y, the "adjacent" side is cos(t) = x, and the hypotenuse is 1 Explanation Change to sines and cosines then simplify 1 tan2x = 1 sin2x cos2x = cos2x sin2x cos2x but cos2x sin2x = 1 we have ∴ 1 tan2x = 1 cos2x = sec2x Answer link Simplify tan^2 x sec^2 Ans 1 Use trig identity 1 tan^2 x = sec^2 x tan^2 x sec^2 x = 1
Notice that for $\theta = , 40,$ and $80$ degrees you have $\tan^2(3\theta) = 3$ The tangent triple angle formula, which you can get from the tangent angle addition formula, says that $$\tan(3\theta) = {3\tan(\theta) \tan^3(\theta) \over 1 3 \tan^2(\theta)}$$ So the equation $\tan^2(3\theta) = 3$ can be expressed as $$(3\tan(\theta) \tan^3(\theta))^2 = 3(1 3 Evaluate (i) tan{2 tan^1 (1/5) (π/4)} (ii) tan{(1/2) cos^1 (√5/3) asked in Inverse Trigonometric Functions by Aryan01 ( 501k points) inverse trigonometric functions Transcript Example 14 Show that tan 3 tan 2 tan = tan 3 tan 2 tan We know that 3 = 2 Therefe, tan 3 = tan (2 ) tan 3 = tan 2 tan 1 tan 2 tan tan 3 tan 3 tan 2
